Referring to the drawings, a label apparatus LB for a peg hook according to an exemplary embodiment in the present disclosure includes a body 100 and a holder 200.

The body 100 includes a display unit 120 on which information of a product 10 is displayed. At this time, the display unit 120 is formed on the front side of the body 100, and is a portion in which a name and specific information of the product 10 are electronically displayed.

In addition, the holder 200 is provided at one end portion 101 of the body 100.

Here, one end portion 101 of the body 100 is specifically one end portion 101 of the body case 110, which refers to an upper portion of the body 100 in a state in which the label apparatus LB for a peg hook is caught on the peg hook 20 to be disposed in a longitudinal direction as shown in FIG. 2.

The holder 200 is configured to be caught on an end portion 22 of the peg hook 20.

At this time, the peg hook 20 has a cantilever structure in which one end portion is fixed and the other end portion 22 is not supported, and one end portion is connected and fixed to a wall or a vertically arranged frame (not shown) and the other end portion 22 is not supported by another member.

The end portion 22 of the peg hook 20 described later refers to the other end portion 22 that is not supported by another member, which is first inserted into a hook hole 10a of the product 10 to hang the product 10 on the peg hook 20.

As shown in FIG. 2, the end portion 22 of the peg hook has a U-shape in plan view, has a structure disposed in a transverse direction, and specifically, is bent from the body 21 of the peg hook 20 to be disposed inclined upwardly to a certain extent. That is, the transverse arrangement structure of the end portion 22 of the peg hook 20 is a structure that is substantially slightly inclined upwardly, and the transverse arrangement structure in the present disclosure refers to a laterally extending structure, in abroad sense, including even an inclined structure, except for a vertically arranged structure.

As shown in FIGS. 2 and 5 through 8, the holder 200 is detachably provided in one end portion 101 of the body 100, and includes a first engaging portion 210 and a second engaging portion 220. At this time, the first engaging portion 210 and the second engaging portion 220 are configured to form an engaging hole 200a through which the peg hook 20 described above is caught. To this end, one end portions of the first engaging portion 210 and second engaging portion 220 are rotatably connected to each other, and the other end portions are assembled to each other.

The first engaging portion 210 includes a first engaging portion 211 and a first clamping portion 212.

The first engaging portion 211 is formed with a first curved recess 211a for the engaging hole 200a. The first curved recess 211a has a semicircular cross-section or is a recess similar to a semicircular shape. The first curved recess 211a is disposed to be adjacent to and facing a second curved recess 221a to be described later, and when the first curved recess 211a is combined with the second curved recess 221a, the engaging hole 200a is formed.

The first clamping portion 212 is connected to the first engaging portion 211, and two first clamping portions 212 are spaced apart from each other to be detachably insertedly fixed to the fastening hole 101a. At this time, the fastening hole 101a may be formed in one end portion 101 of the body 100, that is, an upper portion of the body 100 as shown in the drawing.

Specifically, a length of the first clamping portion 212 in an insertion direction with respect to the fastening hole 101a is longer than a through-length of the fastening hole 101a. Here, the first clamping portion 212 may have a first engaging end 212a formed to be relatively thick outwardly at an end, and the first engaging end 212a may be tapered toward the end.

When the two first clamping portions 212 configured as described above are inserted into the fastening hole 101a of the body 100, the two end portions of the two first clamping portions 212 pass through the fastening hole 101a to escape outwardly from the fastening hole 101a, and at this time, the two end portions of the two first clamping portions 212 are caught on the edge of the fastening hole 101a by the two first engaging ends 212a formed at the two end portions, thus being clamped.

The first engaging end 212a is tapered toward the end, so that when the first clamping portion 212 is inserted into the fastening hole 101a of the body 100, the first engaging end 212a which is first forcibly inserted may be easily inserted into the fastening hole 101a. Conversely, when the first clamping portion 212 is desired to be separated from the one end portion 101 of the body 100, a user may remove the first clamping portion 212 from the fastening hole 101a, while pressing the two first engaging ends 212a in a direction toward each other.

The first engaging portion 210 may have a first reinforcing portion 213 connecting both sides of the two first clamping portions 212. An assembly hole 210a may be formed between the two first clamping portions 212. The assembly hole 210a provides a space in which the first clamping portion 212 is slightly bent to enter when the first engaging end 212a of the first clamping portion 212 is forcibly inserted into the fastening hole 101a. The first reinforcing portion 213 connects both sides of the two first clamping portions 212 to reinforce durability, so that the first clamping portion 212 is not damaged during bending.

A side surface of the connection portion 214 between the first engaging portion 211 and the first clamping portion 212 may be formed parallel to an end side surface 101b of the one end portion 101 of the body 100. When the first clamping portion 212 is assembled in the fastening hole 101a, the side surface of the connection portion 214 between the first engaging portion 211 and the first clamping portion 212 is adjacent to one end portion 101 of the body 100, that is, the end side surface 101b of the upper portion of the body 100 in the drawing. At this time, when the side surface of the connection portion 214 of the first engaging portion 211 and the first clamping portion 212 is formed to be parallel to the end side surface 101b of the one end portion 101 of the body 100, the first clamping portion 212 may be firmly fixed to the body 100, and furthermore, the holder 200 may be firmly fixed to the body 100.

As described above, in the present disclosure, the first clamping portion 212 of the holder 200 is detachably assembled to the fastening hole 101a, so that the holder 200 may be detachably attached to one end portion 101 of the body 100. Due to this, the label apparatus LB for a peg hook according to the present disclosure may be caught on the peg hook 20 by the holder 200 to be used as shown in FIG. 1, or as shown in FIG. 10, only the body 100, without the holder (200 of FIG. 1), may be caught on the peg hook 20 to be used. In the present disclosure, when only the body 100 is used, the end portion 22 of the peg hook having a straight shape may be inserted into the fastening hole 101a formed in the body 100 to be caught on the peg hook 20. Furthermore, although not shown in the drawing, when only the body 100 is used, the body 100 may be wound with a string or line through the fastening hole 101a to be hung on a product, such as clothes or a bag.

The second engaging portion 220 includes a first engaging portion 221 and a first clamping portion 222.

The second engaging portion 221 includes a second curved recess 221a for the engaging hole 200a. The second curved recess 221a has a semicircular cross-section or a recess similar to a semicircular shape. The second curved recess 221a is disposed to be adjacent to and face the first curved recess 211a, so that when the second curved recess 221a is combined with the first curved recess 211a, an engaging hole 200a is formed.

The second clamping portion 222 is connected to the second engaging portion 221, and two second clamping portions 222 are spaced apart from each other to be detachably insertedly fixed to the assembly hole 210a of the first engaging portion 210.

Specifically, a length of the second clamping portion 222 in an insertion direction with respect to the assembly hole 210a is longer than a through-length of the assembly hole 210a. Here, the second clamping portion 222 may have a second engaging end 222a formed to be relatively thick outwardly at an end portion, and the second engaging end 222a may be tapered toward the end.

When the two second clamping portions 222 configured as described above are inserted into the assembly holes 210a of the first clamping portions 212, two end portions of the two second clamping portions 222 may pass through the assembly hole 210a to escape outwardly from the assembly hole 210a, and at this time, the two second clamping portions 222 are engaged with the edge of the assembly hole 210a by the two second engaging ends 222a formed at the two end portions to be clamped. The second engaging end 222a is tapered toward the end, so that when the second clamping portion 222 is inserted into the assembly hole 210a of the first clamping portion 212, the second engaging end 222a which is first forcibly inserted may be easily inserted into the assembly hole 210a. Conversely, when the second clamping portion 222 is desired to be separated from the first clamping portion 212, the user may remove the second clamping portion 222 from the assembly hole 210a, while pressing the two second engaging ends 222a in a direction toward each other.

The second engaging portion 220 may include a second reinforcing portion 223 connecting both sides of the two second clamping portions 222. An inner recess 220a may be formed between the two second clamping portions 222. The inner recess 220a provides a space in which the second clamping portion 222 is slightly bent to enter when the second engaging end 222a of the second clamping portion 222 is forcibly inserted into the assembly hole 210a. The second reinforcing portion 223 connects both sides of the two second clamping portions 222 to reinforce durability, so that the second clamping portion 222 is not damaged during bending.

As described above, in the present disclosure, the second clamping portion 222 is detachably assembled to the first clamping portion 212, so that the end portion 22 of the peg hook may be disposed between the first engaging portion 211 and the second engaging portion 221. That is, after the end portion 22 of the peg hook 20 is disposed in the first curved recess 211a of the first engaging portion 211, the second clamping portion 222 is assembled to the first clamping portion 212 so that the second engaging portion 221 covers the first engaging portion 211, and accordingly, as the end portion 22 of the peg hook 20 is disposed between the first curved recess 211a of the first engaging portion 211 and the second curved recess 221a of the second engaging portion 221, the holder 200 may be caught on the end portion 22 of the peg hook 20.

Meanwhile, as shown in FIG. 9, in the label apparatus LB for a peg hook according to the present disclosure, thicknesses T1 and T2 of the body 100 and the holder 200 are lower than a thickness T3 of the hook hole 10a of the product into which the peg hook 20 is inserted. As the peg hook 20 is inserted into the hook hole 10a of the product 10, the product is caught on the peg hook 20. At this time, the thickness T3 of the hook hole 10a is greater than the thickness of the peg hook 20, so that the product 10 may easily move along the peg hook 20.

In the present disclosure, since the thicknesses T1 and T2 of the body 100 and the holder 200 are formed to be smaller than the thickness T3 of the hook hole 10a described above, the user may grip the product 10 and easily insert the label apparatus LB for a peg hook and the peg hook 20 into the hook hole 10a of the product 10 or may grip and easily remove the product 10 from the peg hook 20.

In addition, widths W1 and W2 of the body 100 and the holder 200 are narrower than a width W3 of the hook hole 10a of the product 10 into which the peg hook 20 is inserted. As the peg hook 20 is inserted into the hook hole 10a of the product 10, the product 10 is caught on the peg hook 20. At this time, since the width W3 of the hook hole 10a is greater than the width of the peg hook 20, the product 10 moves easily along the peg hook 20.

In the present disclosure, the widths W1 and W2 of the body 100 and the holder 200 are smaller than the width W3 of the hook hole 10a described above, so that the user may grip the product 10 and insert the label apparatus LB for a peg hook and the peg hook 20 into the hook hole 10a of the product 10 or may grip the product 10 and easily remove the product 10 from the peg hook 20.

Also, as shown in FIG. 3, a total length L of the body 100 and the holder 200 in a direction in which the body 100 and the holder 200 are connected may be greater than one time and smaller than three times the width W1 of the body 100. If the total length L of the body 100 and the holder 200 is smaller than one time the width W1 of the body 100, the display unit 120 may become too small and information of the product (10 in FIG. 1) may not be sufficiently displayed. In addition, when the total length L of the body 100 and the holder 200 is greater than three times the width W1 of the body 100, the longitudinal length may become too long and the displayed product 10 may be covered so that the product 10 may not be easily identified.

Meanwhile, the body 100 may include a body case 110, the display unit (120 in FIG. 3), a battery 130, and a battery case 140, as shown in FIGS. 4, 7, and 8.

The body case 110 is provided with a holder 200 at one end portion 101, and the display unit 120 is provided on the front portion of the body case 110.

In addition, the battery 130 is disposed inside through an open rear portion of the body case 110, and the battery case 140 is installed on the open rear portion of the body case 110 to cover the battery 130.

At this time, the battery case 140 may be formed of a stainless steel material. As the battery 130 has a thickness greater than or equal to a certain thickness, the battery case 140 needs to be formed to have a very thin thickness in order to reduce the overall thickness of the body 100. To this end, since the battery case 140 is formed of stainless steel, which is a high-strength material, durability may be secured even with a very thin thickness. Furthermore, as the stainless steel material has excellent corrosion resistance, the battery case 140 is not easily oxidized.

Meanwhile, the present disclosure may further include a notification lamp 150 as shown in FIGS. 2 and 3.

The notification lamp 150 is formed on a front portion of the body 100 in which the display unit 120 is formed, and is connected to an application through the wireless Internet.

The notification lamp 150 plays a role of notifying by light emission when the product (10 in FIG. 1) displayed on the peg hook 20 is the product 10 selected in the application.

Also, in the present disclosure, as shown in FIG. 4, a screen switching button 160 may be formed.

The display unit (120 in FIG. 3) is configured to be able to switch a plurality of screens, and the screen switch button 160 may be formed to operate the screen switching.

Specifically, the screen switching button 160 is formed on a rear portion of the display unit 120 in the body 100, and has a structure electrically connected to the display unit 120 to switch the screen of the display unit 120.

Furthermore, this screen switching button 160 may be formed of a built-in structure not to protrude to the outside of the body 100, and in this case, when a portion of an outer surface of the body 100 corresponding to the screen switching button 160, that is, a portion marked ‘push’ in the drawing, is pressed, the internal screen switching button 160 may be pressed.

The label apparatus for a peg hook according to the present disclosure has an effect that the holder is detachably provided at one end portion of the body, so that the label apparatus for a peg hook may be caught on the peg hook by the holder to be used, or only the body, without a holder, may be caught on the peg hook to be used.

In addition, in the present disclosure, the thickness of each of the body and the holder is formed smaller than the thickness of the hook hole and the width is formed smaller than the width of the hook hole, so that the user may grip the product and easily insert the label apparatus for a peg hook of the present disclosure and the peg hook into the hook hole of the product, or the user may grip the product and easily remove the product from the peg hook.

In addition, according to the present disclosure, as the total length of the body and the holder is greater than one time and less than 3 times the width of the body, covering the displayed product may be minimized, while securing the display unit having an appropriate size, so that the product may be easily identified.

On the other hand, in the present disclosure, since the battery case is formed of stainless steel, the durability may be secured even with a very thin thickness and, since corrosion resistance is excellent, oxidation of the battery case may be prevented.

While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the scope of the present disclosure as defined by the appended claims.
